[0042] . THE figures 1 à 4 These figures illustrate a representation of a measuring station 100 according to at least one embodiment of this description. The measuring station 100 is primarily in the form of a base 102 on which a user can place their feet, for example, flat. The user can be on the measuring station or seated in a chair. In the normal operating position, the user's feet are placed flat on the measuring station 100. The thickness of the base 102 is, for example, less than 10 cm, or even 6 cm. The measuring station 100 includes one or more sensors 104 capable of measuring a user's physiological information.

[0043] In one embodiment, certain sensors 104 (for example, electrodes) are mounted on a substrate 106 of the base 102, the substrate being configured to receive the feet of a user. The substrate can be a rigid plate, as illustrated in the figures, and referred to as the measuring plate 106. The measuring plate 106 defines a plane parallel to an XY plane. The measuring plate 106 can be made of glass. However, the substrate can be deformable under the weight of the user. The substrate 106 can be mounted on a base 108, for example, a rigid base, or on feet (not shown). In the case of a base 102 functioning as a bathroom scale, sensors are positioned between the substrate 106 and the base 108 (a so-called "sandwich" architecture) or between the substrate 106 and the feet (a so-called "feet" architecture). The sensors can be load cells (usually four) which allow us to obtain a weight, and therefore a mass of a user.The base 108 can be made of metal (aluminum, steel, etc.) or plastic.

[0044] As seen in figure 2 The measuring station 100 also includes a support plate 202, which can be attached to the measuring plate 106. The support plate 202 is designed to receive part of the electronics of the measuring station 100, notably via a printed circuit board (PCB) (" printed circuit board " mounted on the support plate 202. The support plate 202 is therefore positioned between the base 108 and the measuring plate 106.

[0045] In a pedestal architecture, two groups are defined as moving relative to each other: the feet (fixed group) and everything else (mobile group). Load cells mechanically connect these two groups. The support plate, if present, is then generally hidden by an external cover attached to the measuring plate. Visually, only the moving part is usually visible.

[0046] In a sandwich structure, two groups are defined as moving relative to each other: the base 108 (and associated elements) on one hand (fixed group), and everything else on the other (mobile group). Load cells mechanically connect these two groups. Visually, both groups are generally visible.

[0047] The measuring station 100 also includes a handle 110, suitable for gripping by at least one hand of the user, illustrated in figures 3 And 4The 110 handle can be connected to the measuring station by a 302 cable (visible on the figure 3 The 302 cable allows, in particular, the transmission of electrical signals between the handle 110 and the base 102. To have a practical measuring station 100 without a loose cable, the 302 cable can extend and retract (for example, wind and unwind) inside the base 102. For this purpose, a reel (visible on the figure 8 ) is arranged in a space provided between the substrate 106 and the base 108. At least two positions are thus defined for the handle: a stowed position (visible in figures 1 And 2 ) and a deployed position (visible in figure 3 The base 102 also includes a handle support 112 which can hold the handle 110 in its stowed position. The handle support 112 is mounted on the substrate 106. The handle support 112 can be an added component on the measuring plate 106. For example, the handle support 112 can be glued to the measuring plate 106 (especially when it is made of glass) or screwed in place. This will be described in more detail later. The handle 110 also includes at least one sensor 402.

[0048] The 110 handle is used to perform at least one of the following measurements: ECG (1-channel ECG between both hands or multi-channel ECG with other limbs), BIA (also known as "segmental"), IPG. The sensors for the 110 handle are selected from among the following: optical sensor for PPG and electrodes.

[0049] The base 102 can include a display 114 (for example, a screen or an LED or e-ink display) to show information to the user. The display 114 is shown as a dotted line on the figure 1 because, in the example of the figures, it is not or barely visible when it is switched off.

[0050] The base 108 of the base 102 may include a chamfer 204 to facilitate gripping the measuring station 100 when it is on the ground.

[0051] In one embodiment, the base 102 has an essentially rectangular shape in an XY plane. The base 102, for example, has an essentially parallelepiped shape in XYZ space.

[0052] When the measuring station 100 is positioned flat, the measuring plate 106 is parallel to an XY plane. The measuring station 100 has a longitudinal dimension in an XY plane and a transverse dimension in an XY plane orthogonal to the longitudinal direction. Height refers to the dimension along the Z-axis (also called thickness); width refers to the transverse dimension along the X-axis; and length refers to the longitudinal dimension along the Y-axis. In normal use, the user's feet are positioned along the Y-length of the base 102.The edge of measuring station 100 (or of base 102, or of measuring plate 106) that is closest to the anterior part of the foot in normal use (i.e. the toes) is called the anterior edge 206 and the opposite edge of measuring station 100 (or of base 102, or of measuring plate 106), that is closest to the posterior part of the foot in normal use (i.e. the heel) is called the posterior edge 208. A median axis can be defined, according to the length Y (longitudinal), around which the measuring plate 106 is symmetrical and which allows us to define a left part, intended for the left foot, and a right part, intended for the right foot. The width X102 of the base 102 can be between 330 and 400mm (for example about 357mm) and the length of the base Y102 can be between 300 and 360mm (for example about 325mm).The length and / or width of the measuring plate 106 may be slightly less than those of the base 108, so that the measuring plate 106 is slightly recessed relative to the base 108. In this case, the length and width of the base 108 correspond respectively to the length and width given above for the base 102. Such a design protects the measuring plate 106 from impacts and contact with the external environment. French patent application FR2106653 describes such a solution.

[0053] Specifically, as illustrated in figure 2 The height Z102 of the base 102 can be between 20 and 35 mm (for example, between 35 and 40 mm), and the maximum height Z100 of the measuring station 100 can be between 45 and 55 mm (for example, 51 mm). As illustrated in the figures, only the handle support 112 and the handle 110 protrude in the Z direction relative to the measuring plate 106. In detail, the height H108 of the base 108 can be between 10 and 20 mm (for example, 18 mm), the height Z202 of the support plate 202 can be between 3 and 6 mm (for example, 4 mm), and the height Z106 of the measuring plate 106 can be between 4 and 8 mm (for example, 6 mm).

[0054] The 302 cable can have a length between 50cm and 120cm. The length is chosen so that most users can grip the handle while standing with their hands downwards (at rest).

[0055] The measuring station 100 could, however, have different shapes and / or dimensions, provided that the shape and / or dimensions allow for obtaining the measurements described herein. In particular, the base 102 could have an oval or more rounded shape in the XY plane.

[0056] The measuring station 100 can have a mass between 3 and 6 kg (for example between 4 and 5 kg).

[0057] Thanks to the sensor(s) on the base 102 and / or the sensor(s) on the handle 110, the measuring station 100 can perform a series of measurements on the user. Specifically, the sensors 104 used include electrodes formed from electrically conductive paths mounted on the substrate 106 and / or the handle 110 (metal inserts, metal deposits, etc.). Some measurements may require only sensors on the base 102, other measurements may require only sensors on the handle 110, and still other measurements may require both sensors on the handle 110 and the base 102.

[0058] The measuring station 100 can thus perform an ECG using the handle 110 (e.g., a 1-lead ECG), or an ECG using the handle 110 and the base 102 (e.g., a multi-lead ECG, such as a six-lead ECG). The measuring station 100 can thus perform a body impedance analysis (BIA) using the handle 110 and / or the base (inter-day BIA and / or segmental BIA). The measuring station can thus perform an IPG in the leg arc (" between legs " or IPG in the foot.

[0059] The sensors may include electrodes capable of measuring and / or applying a voltage (DC or AC) and / or a potential (DC or AC), and / or injecting and / or receiving a current (DC or AC). The functions of these electrodes may be selected from the following list: i+ and i-, for injecting AC current into a user's body; V+ and V-, for measuring a potential difference in a user's body; RA, LA, and LL, for measuring an electric current flowing through a user's body. Electrodes i+ and i-, V+ and V- are used for a BIA, IPG, or ICG; electrodes RA, LL, and LL are used for an ECG.

[0060] In particular, measuring station 100 is configured to perform various measurements. As the number of electrodes is limited (due to surface area and quantity considerations), measuring station 100 features a specific electrode arrangement with a switch.

[0061] As previously mentioned, the sensors may include load cells, through which the measuring station 100 can measure a weight and perform a BCG.

[0062] The 110 handle is illustrated in detail in figure 4 The 110 handle allows the 100 measuring station to perform a wider variety of measurements or more comprehensive measurements, thanks to an electrical connection with at least one hand, or even both hands. In particular, segmental BIA and / or multi-channel ECG are made possible by adding the 110 handle to the 102 base. The 402 sensors of the 110 handle include, for example, electrodes capable of measuring and / or applying voltage and / or potential and / or injecting and / or receiving current.

[0063] In one embodiment, in the stowed position, the handle 110 is located near the front edge 206. This means that the handle support 112 is located near the front edge 206. For example, the handle support is located at most between 1 and 3 cm from the front edge 206.

[0064] In one embodiment, the handle 110 comprises four electrodes, arranged in two pairs: one pair for the left hand and one pair for the right hand. For this purpose, the electrodes of the handle are designated as: electrodes LH1, LH2, side by side on a left portion of the handle 110, and electrodes RH1, RH2, side by side on a right portion of the handle (by left and right portions, respectively, is understood the part of the handle intended to be in contact with the left and right hands, respectively). "Side by side" here means with a space between the electrodes to isolate them from one another. The electrodes are therefore arranged end to end between two ends of the handle 110. When the handle 110 is straight, the electrodes are arranged end to end along the main direction of the handle 110.Electrodes LH1 and RH1 are positioned axially on one end of the handle; electrodes LH2 and RH2 are positioned axially on the center of the handle. Therefore, the electrodes are, in order: LH1, LH2, RH2, RH1.

[0065] In one embodiment, the sensors 402 of the handle 110, when used as electrodes, are implemented as several metallic inserts within the handle 110. Materials suitable for these metallic inserts include stainless steel, titanium, brass, ITO, or conductive plastics. For signal processing and / or acquisition, particularly of ECG signals, the handle 110 may incorporate processing electronics (operational amplifier follower, etc.), specifically for ECG. It is generally preferable to amplify the signal as close as possible to the electrodes, as the cable can pick up ambient noise.

[0066] . There figure 5 This illustrates a schematic view of the overall architecture 500 into which the measuring station 100 can be inserted. This overall architecture forms a system comprising the measuring station 100. In particular, the measuring station 100 can communicate with third-party devices via a communication network 510, which is, for example, a wireless network (specifically, a network compatible with at least one of the following communication protocols: Bluetooth, Wi-Fi, cellular, etc.). The third-party devices may include a server 520 and a mobile terminal 530 (smartphone, etc.). The server 520 may include control circuitry 522, including a processor 524 and memory 526, and an input / output (I / O) interface 528, which allows the control circuitry to receive and send data to the communication network 510.The mobile terminal 530 may include control circuitry 532, including a processor 234 and memory 236, and an input / output (I / O) interface 538, which allows the control circuitry to receive and send data. The server 520 is a remote server, for example, located in a data center. The mobile terminal 530 further includes a user interface 540 (UI) configured to display information to the user and, if necessary, allow the user to enter information (such as height, gender, etc.). In particular, the control circuitry 532 is configured to run an application managing the environment of the measurement station 100. The mobile terminal 530 is a personal object of the user, usually kept near them.

[0067] The measuring station 100 can communicate with the server 520 and / or the mobile terminal 530. In one embodiment, the measuring station 100 can communicate directly with the mobile terminal 530, for example, via Bluetooth or Bluetooth Low Emission (BLE). This communication can be implemented during the installation of the measuring device 100, in particular to pair it with the mobile terminal 530 and / or to configure a connection to the server 520 that does not go through the mobile terminal 530 and / or as a backup in case of a failed communication with the server 520. In another embodiment, the measuring station 100 can communicate directly with the server 520, without going through the mobile terminal 530. This communication allows the user to use the measuring station even without having their mobile terminal 530 nearby.

[0068] The measuring station 100 also includes a control circuit 550 with a processor 552 and a memory 554, and an input / output (I / O) interface 556, which allows the control circuit to receive and send data to the communication network 510. The processor 552 is configured to process data obtained from the sensors 104. In particular, the processor 552 can execute instructions from a program stored in the memory 554. The control circuit 550 may include a microcontroller, which integrates the processor 552, the memory 554, and the input / output interface 556. The control circuit 550 may also include an analog front end (AFE). The control circuit 550 may also include an analog-to-digital converter (ADC).The measuring station 100 includes a voltage source 558 (e.g., DC) and a current source 560 (e.g., AC). The measuring station 100 also includes a voltmeter 562 (or any system capable of measuring voltage). The voltmeter 562 can be integrated into the AFE. The current source 560 can be integrated into the AFE, and the voltage source 558 can be integrated into the microcontroller MCU (e.g., via a digital-to-analog converter, DAC). Some sensors 104 (especially the sensors 402 of the handle 110 of the . figure 4 or the 602 electrodes of the 110 handle on the figure 6A ) are connected to the control circuitry 550 (for example, to the MCU or the AFE). The measurement station 100 includes a battery 564, capable of supplying power to the various components of the measurement station 100.

[0069] The 550 control circuitry and other electronic components can be mounted on a printed circuit board (PCB) (“ printed circuit board " , which is, for example, attached to the support plate 202. Connectors link the electrical conductive paths from the measuring plate to the PCB. In order to change the electrode connections to the various components of the measuring station 100, the measuring station includes a switch 566. The switch 566, which can include a plurality of switches driven by the MCU, will be described in more detail later.

[0070] The 550 control circuitry includes, for example, an ECG acquisition system, an impedance measurement system (for BIA or IPG), and an ESC system (for ESC). The ECG acquisition system includes electrodes (represented by 602 on the diagram). figures 6a et 6b and 402 on the figure 4 ) and an ECG 568 electrical circuit (which notably integrates various amplification and / or filtering stages and a demodulator); the impedance measurement system notably includes electrodes (represented by 602 on the figures 6a et 6b and 402 on the figure 4 The ESC system comprises electrodes, the current source 560, the voltmeter 562, and an impedance measurement circuit 570 that connects the electrodes to the current source and the voltmeter (which incorporates various amplification and / or filtering stages). The ESC system includes electrodes, the voltage source 558, and an ESC circuit 572 (which incorporates various electronic components, including resistors). The switch 566 allows the electrodes to be connected to the various circuits 568, 570, and 572 mentioned above, or to be disconnected from all the electrodes of the control circuitry 550.

[0071] The 550 control circuitry is essentially located in the base 102, with the exception of a few components (amplification, filtering and switches) arranged in a PCB in the handle 110, to process the signals before passing them through the cable 302.

[0072] As mentioned previously, the 100 measurement station also includes a display 114, such as a screen (OLED / PMOLD, Retina, etc.), to show information to the user. Alternatively, the 100 measurement station does not include a display.

[0073] The 110 handle is illustrated in detail in figures 4 , 6 And 7The handle 110 allows the measuring station 100 to perform a wider variety of measurements or more comprehensive measurements, thanks to an electrical connection with at least one hand, for example, both hands. In particular, segmental BIA and / or multi-channel ECG are made possible by adding the handle 110 to the base 102. The sensors 402 of the handle 110 include, for example, electrodes 602 capable of measuring and / or applying voltage and / or potential and / or injecting and / or recovering current.

[0074] As described previously, in one embodiment, the handle 110 comprises four electrodes, arranged in two pairs: one pair for the left hand and one pair for the right hand. For this purpose, the electrodes of the handle are designated as: electrodes LH1, LH2, side by side on a left portion of the handle 110, and electrodes RH1, RH2, side by side on a right portion of the handle (by left portion, respectively right, it is understood that the portion of the handle is intended to be in contact with the left hand, respectively right hand; and by side by side includes a spacing between the electrodes). Electrodes LH1 and RH1 are positioned axially on the end side of the handle; electrodes LH2, RH2 are positioned axially on the center side. Thus, the electrodes are, in order: LH1, LH2, RH2, RH1. The 302 cable enters the handle between the LH1, LH2 electrodes on one side and the RH1, RH2 electrodes on the other.

[0075] As illustrated in figure 6B The electrodes 602 are positioned offset from the point where the cable 302 enters the handle 110. In the case of a cylindrical handle with axis A parallel to the transverse direction X of the measuring station 100 in its stowed position, where the insertion position of the cable 203 in the handle 110 defines 0°, the electrodes extend over an external surface of the handle 110 between -45° and +90° (counterclockwise with respect to the orthonormal coordinate system XYZ), or even between -30° and 80°. In the embodiment shown in the figures, the electrodes extend from -30° to +79° (angle covered by the electrodes of 109°, plus or minus 1°). The angles are defined in a cross-section of the handle 110 (a cutting plane orthogonal to axis A, therefore a cutting plane in YZ when the handle 110 is positioned in the handle support 112). Positive angles between 0 and +180° are oriented towards the edge nearest to the base 102.In other words, in the stowed position, the electrodes extend more on the handle on the anterior edge 206 side of the base 102 than on the posterior edge 208 side.

[0076] More generally, for any shape of the handle (straight, slightly curved, non-cylindrical, etc.), the electrode positioning can be defined as follows. The handle 110 includes a centerline 610, which is a line passing through the center of the volume defined by the handle 110; that is, a line defined by the centroids of successive cross-sections of the handle 110 (centroid of the curve defined by the outer surface of the handle 110 in a cross-section). The handle 110 includes a lower line 612, which is a line defined, for successive sections of the handle 110, by the set of points on the outer surface of the handle 110 that are closest to the measuring plate 106 (in its stowed position). For each cross-section at the midline, the angle passing through the midline and one end of the electrodes 602 on an external surface of the handle 110 is defined.The angle 0° is defined as the angle between the median and the bottom line; positive angles are defined from 0° towards the front edge 206, and negative angles are defined from 0° towards the rear edge 208 (the angles therefore extend from -180° to +180°). The cable 302 is inserted into the handle 110 at the angle 0° (the point at which the cable 302 enters the handle 110 is therefore at 0°). For each cross-section at the median line 610 that includes a portion of electrode 602, the electrode 602 extends at most over an area of ​​the handle between -45° and +90°, specifically between -30° and 80°. In one embodiment, the electrodes extend from -30° to +79° (total angle covered by the electrodes of 109°, plus or minus 1°).

[0077] This electrode positioning offers several advantages. When gripping the handle 110, the cable 302 generally remains downwards, aligned with the vertical Z axis. Consequently, firstly, with a natural and intuitive grip, the electrode positioning allows for optimized contact with the fingers, ensuring contact between the electrodes and all fingers: the phalanges of the longest fingers, and the phalanges or phalanges of the shortest fingers. Secondly, by preventing contact between the finger phalanges, the handle 110 can be used with rings. Thirdly, the electrodes are positioned downwards, meaning they are oriented towards the ground: the weight of the handle, the cable, and possibly a cable tension force all contribute to maintaining contact between the electrodes and the fingers, which wrap under the handle 110 and thus over the electrodes.Fourth, the position of the four electrodes along direction A allows the electrodes to all be in contact with one hand as part of a natural and intuitive grip on handle 110.

[0078] The handle 110 may include a main body 404 on which the electrodes and other components (electronics, attachment, etc.) are mounted. The main body 404 may have an elongated shape along a longitudinal axis (which is parallel along the X direction in the stored position), for example, generally cylindrical and more specifically cylindrical of revolution. The shape is chosen to be easily grasped by a user. To facilitate assembly, the main body 404 may include a first part 702 and a second part 704. The first part 702 may receive the electrodes 402, and the second part 704 may be mounted on the first part 702. In particular, the second part 704 may include a cylindrical section (for example, of revolution) with two ends (for example, flat or rounded).An area of ​​the side wall of the cylindrical section may be absent (for example from one end to the other) in order to accommodate the first part 702 of the main body 404. A plastic material may be used for the main body, in order to keep the handle light (in case of a fall) and to properly insulate the electrodes 402 from each other.

[0079] In one embodiment, the electrodes 402 are made in the form of several metallic inserts in the main body 404. Materials that can be used for the metallic inserts include stainless steel, titanium, brass, ITO (indium tin oxide), nickel (or nickel alloy), or conductive plastics. For signal processing and / or acquisition, particularly of ECG signals, the handle 110 may include processing electronics (amplification, filtering, etc.), especially for ECG. It is generally preferable to amplify the signal as close as possible to the electrodes because the cable can pick up ambient noise.

[0080] In the stowed position, the first part 702 is opposite the base 102 and the second part 704 is visible. The electrodes 402 are thus positioned against the handle support 112.

[0081] In one embodiment, the handle 110 is removable, particularly for repair purposes. To this end, the handle 110 includes a fastening system 604 for connecting the handle 110 to the cable 302. The fastening system 604 allows the handle 110 to be replaced without changing the cable 302. The fastening system 604 can be mounted in the first part 702 of the handle. This positions the electrodes on the side of the cable 302, ensuring a natural contact position between the electrodes 402 and the user's fingers. The fastening system 604 may include a jaw 606, 608 that fits around a stopper mounted on the cable 302.

[0082] In one embodiment, the handle support 112 and the handle 110 include a magnetic attachment system (for example, using at least one permanent magnet). A magnetic material is provided in the support 112, and a magnet is mounted in the handle 110 (or vice versa). The magnetic attachment systems also serve as a keying device when positioning the handle 110 on the handle support 112 (the left side of the handle cannot be placed on the right side of the handle support due to polarity differences). Neodymium magnets may be used.

[0083] As mentioned previously, cable 302 can be stored in base 102 (in the stored position, visible in figures 1 And 2 ) and be outside of base 102 (in deployed position, visible in figure 3 ).

[0084] To allow the cable 302 to more naturally stow itself in the stowed position, the end of the cable 302 attached to the handle 110 extends orthogonally with respect to a surface of the handle. In particular, the handle shown in the figures has a cylindrical shape: the cable 302 therefore extends radially with respect to the cylinder.

[0085] The change of position between a stowed and an extended position therefore involves a movement of the cable 302 relative to the base. For safety and practical reasons, it is desirable that the cable 302 be almost entirely housed within the base 102 in the stowed position. To enable this without any particular effort from the user, a return mechanism 802 is mounted in the balance. In one embodiment, this return mechanism is a winder, meaning that the cable 302 winds and unwinds when the user prepares to use the handle 110. figure 8 This illustrates the positioning of such a winder 802 (shown without its cover) in the base 102. The winder 802 is, for example, mounted on the support plate 202, which may include a through opening 902 to house the winder (to minimize the thickness of the base 102). The winder 802 may include mounting tabs that are screwed to the support plate 202. The winder 802 comprises, for example, a fixed portion and a moving portion, with a spring between the two to provide a return function when the handle 110 is in the extended position or in an intermediate position. Document WO2021 / 082876 describes an example of a winder mechanism integrated into a bathroom scale.

[0086] To guide the cable 302 between the reel 802 and the handle 110, different solutions are proposed, which can be implemented together or separately.

[0087] The measuring plate 106 includes a through-hole 1102 for the passage of the cable 302. The radial orientation of the cable 302 relative to the handle cylinder allows the cable to be inserted directly into the through-hole 1102 of the measuring plate 106. The through-hole 1102 is, for example, cylindrical (i.e., straight). The through-hole 1102 can be orthogonal to the measuring plate 106 (parallel to the Z-axis, and not at an angle) to facilitate pulling the handle 110; for example, a straight cylindrical shape. The through-hole 1102 can have a cross-section equivalent to that of the cable 302 (with a slight functional clearance). For example, the through-hole 1102 is cylindrical. For example, the maximum cross-sectional dimension of the hole is 2 cm or 1 cm.

[0088] In particular, the support plate 202 and the measuring plate 106 each include a through hole 804 and 1102, opposite each other, for the passage of the cable 302.

[0089] The reel 802 winds and unwinds the cable 302 in the XY plane (essentially along the Y axis) while the handle 110 (and therefore the portion of the cable outside the base 102) moves along the Z axis. Consequently, the cable 302 must make one or more changes of direction. Near the opening 804 in the support plate 202, a roller 1002 (or a pulley) is arranged to facilitate the change of direction of the cable 302 (and to prevent friction that damages the cable 302, the support plate 202, and / or the handle support 112, and hinders the winding and unwinding of the cable). The roller 1002 can be a rotating roller or simply a roller with a smooth coating. As illustrated in the figure 10 (which illustrates a portion of the support plate 202), the roller 1002 can be mounted on the support plate 202 (on the underside 1004, i.e., the side facing the ground when the measuring station 100 is in the operating position). The roller 1002 is arranged, along the Z direction, between the cable 302 and the support plate 202 (or the measuring plate 106). A second roller (not shown) can be provided between the roller 1002 and the reel 802 to channel the cable. The second roller can be arranged so that the cable 302 is between this second roller and the measuring plate. Alternatively, the second roller is opposite the first roller 1002. The two rollers are therefore on either side of the cable 302 (along the Z direction). Instead of a roller, a pulley or any element fulfilling a similar function can be used.

[0090] To limit friction as the cable passes through the opening 804 in the support plate 202 and to soften the angle formed by the cable 302, the edges of the opening are chamfered (chamfer 1006 visible in figure 10 ), at least on the underside 1004. Similarly, to limit friction when passing through the orifice 1102 of the measuring plate 106, the edges of the orifice 1102 are chamfered (see figure 11 : chamfer 1106 visible on the upper face 1104 of the measuring plate 106 (i.e., the visible face on which the user places their feet). As the measuring plate 106 may be made of glass and therefore sharp, the opening 1102 is chamfered on both sides (see figure 12 , which presents a magnification in perspective: chamfer 1202 visible on the lower face 1204 of the measuring plate 106, i.e. the invisible face, which is opposite the support plate 202).

[0091] In the example shown in the figures, the handle support 112 is a part attached, for example by gluing, to the upper face 1104 of the measuring plate. The handle support 112 has an elongated shape here. The handle support 112 can form a cradle 1302, of the rounded cradle type. The cradle can have a shape complementary to a portion of the handle 110 (here the first part 702 of the handle 110). In the example shown in figure 6B The cradle 1302 is rounded around a direction axis X. The handle 110, when positioned on the handle support 112, does not touch the measuring plate 106.

[0092] To ensure that the cable 302 is completely invisible when folded, the handle support 112 includes a through-hole 1304, aligned with the hole 1102 in the measuring plate 106. The radial orientation of the cable 302 relative to the handle cylinder allows the cable to be inserted directly into the through-hole 1304 of the handle support 112. The through-hole 1304 can be, for example, cylindrical (i.e., straight). The through-hole 1304 can be perpendicular to the measuring plate 106 (parallel to the Z-axis, and not at an angle) to facilitate pulling the handle 110; for example, a straight cylindrical shape. The through-hole 1304 can have a cross-section equivalent to that of the cable 302 (with a slight functional clearance). For example, the through-hole 1304 can be cylindrical. For example, the maximum cross-sectional dimension of the hole is 2 cm or 1 cm.

[0093] The through-hole 1304 is advantageously positioned at the bottom of the cradle 1302. The bottom of the cradle is defined as the lowest position along the Z direction, i.e., the position closest to the measuring plate 106. Furthermore, the through-hole 1304 can be centered within the cradle along the Y axis. The movement of the cable 302 from the through-hole 1304 of the handle support 112 may become somewhat erratic due to the use of the handle 110 by a user. To further reduce friction, the through-hole 1304 of the handle support 112 is chamfered. In particular, the edges of the through-hole 1304 are chamfered in the Y direction and can also be chamfered in the X direction (even chamfered all the way around). A chamfer 1306 is thus provided on at least one of the two opposite edges along Y of the through orifice 1304.Similarly, a chamfer 1306 can thus be provided on at least one of the two opposite edges along Y of the through orifice 1304.

[0094] The cradle 1302 can extend over an angle at least equal to the negative value of the position of the electrodes 602 on the handle 110 relative to the bottom of the cradle (which corresponds to the angular position of the through-hole 1304 and therefore to the location of the cable 302 in the figures, i.e. -30° in the illustrated example). In other words, in the given example, in a cross-section (a YZ cutting plane), the cradle extends over 30° between its end and the bottom of the cradle (which here corresponds to the angular position of the through-hole 1304).By having a cradle that extends over an angular portion (around an axis parallel to the X direction) at least equal to that of the electrodes, the latter are invisible when the measuring station 100 is observed from the rear edge 208, which corresponds to its most frequent positioning by the user since the front edge 206 is generally against a wall) because they are hidden by the cradle 1302 (see . figure 6B ). This concealment helps increase the retention of the 100 measuring station (i.e., the fact that most users of the 100 measuring station continue to use it after a given period) because the user does not feel they are using a product with a medical or paramedical appearance.

[0095] Similarly, the cradle can extend less than 90°, that is, at an angle of no more than 90°, or even no more than 60°, or even 45°, on either side of the cradle's base (which is defined as 0° – the through-hole also being at 0°), so as not to hinder gripping the handle. Fingers can then slide under the handle to remove it from the handle support 112. The 45° angle allows for easier gripping while concealing the electrodes.

[0096] Thanks to the handle support 112, the design and manufacture of the measuring plate 106 are simplified. Except for the through-hole 1102, the measuring plate 106 can be similar to that of a measuring station without a handle (thus simplifying the processes for having several different models, with and without a handle, for example). Furthermore, by placing the handle 110 on a handle support 112 positioned on the measuring plate 106, the handle 110 is easily grasped by a user, particularly by raising the stored position relative to the measuring plate 106 along the Z direction (i.e., the entire handle is raised relative to the measuring plate 106). The cradle shape 1302 allows the handle 110 to be stored easily and thus not placed on the ground where it risks being damaged, damaging the base 102 or the ground on which it is placed.The arrangement of the cable 310 in the vertical direction 2, in alignment with the through holes 1304 and 1102 of the handle support 112 and the measuring plate 106, helps to simplify the storage position of the measuring station 100 because it is enough to accompany the return force of the reel 802 for the handle 110 to be positioned in the cradle 1302 (in particular due to the positioning of the through hole 1304 at the bottom of the cradle 1302).

[0097] In the description above and in the figures, the handle support is continuous along the X direction. However, it can be discontinuous along this direction. For example, a cradle shape can be created by two or three supports, at the ends and in the middle. This configuration, however, conceals the cable and handle electrodes less.

[0098] In an alternative not included in the claimed invention, the measuring station 100 does not include a handle support, and the handle is placed directly on the measuring plate 106. The latter can be machined or molded to have a shape that allows the handle 110 to be received and held in place. For example, a cradle shape can be made in the glass. The through-hole 1102 is then at the bottom of the cradle. The magnetic attachment system can then be provided in the handle and under the measuring plate.

[0099] In one embodiment, the measuring station 100 has a weighing function to measure the weight, and therefore the mass, of a user. The sensors on the base 100 then include at least one weight sensor or one mass sensor. In particular, a known solution involves using load cells, which convert the deformation of an element into an electrical signal. When the user steps onto the measuring plate 106, their mass generates a force that is absorbed by the measuring plate 106 and then transmitted (directly by contact or indirectly via an intermediate part such as the support plate 202) to at least one load cell. The contact is then transferred to the base 108 (or the feet for the pedestal architecture). Four load cells can be provided, one near each corner of the base 102.When the base 102 is not rectangular, the load cells can be arranged regularly with respect to the geometry (for example with symmetry around median axes).

[0100] In an embodiment illustrated in figures 8 And 9 The support plate 202 includes openings 812 suitable for housing (without contact) the load cells. In this way, the support plate 202 does not interfere with the transfer of force between the measuring plate 106 and the load cells.

[0101] However, in the sandwich architecture, the displacement in the XY plane of the moving assembly (measuring plate 106, support plate 202, and other components, particularly electronic ones) must be limited relative to the fixed assembly (primarily the base 108). This displacement limitation must not, however, affect the weight measurement; that is, it must not interact with the displacement along the Z direction nor absorb any load along the Z direction. Document PCT / EP2017 / 050178 describes a satisfactory solution to this problem. The present description proposes an alternative embodiment. The support plate 202 includes at least one island 808, for example, one island 808 per load cell (four in the figures, one near each load cell). Island 808 is a part of the support plate 202 which is connected to a main body 902 of the base of support plate 202 by an elastic member 904.The elastic member 904 serves to limit the XY displacement of the moving assembly while minimizing interference with the Z-axis movement. The elastic member 904 may include one or more legs extending between the island 808 and the main body 902 of the support plate 202. In the figures, each elastic member 904 comprises four identical legs. Each island 808 is housed in a through-hole formed in the main body 902. The island 808 may have a circular, square, rectangular, or other shape (polygonal, for example, or a shape of revolution), and the through-hole may have a similar shape but be proportionally larger.

[0102] Each island 808 includes a mounting hole 1402, for example in the form of a tapped hole, which is suitable for receiving a rod, for example a screw, which secures the base 108 to the island 808 (via a mounting hole 1502 in the base 108). The screw may be self-tapping. The mounting hole 1402 may be provided in a projection 1404, which both limits the length of the rod and locally increases the thickness of the island 808 (greater rigidity in the connection with the rod).

[0103] However, if a user grasps the measuring station 100 by the measuring plate 106 (which is part of the moving assembly), the entire weight of the fixed part will be transferred through the rod and the island 808. The elastic member(s) 904 are not strong enough to withstand this force (remember that they are not intended to interfere with the weight measurement). The support plate 202 and the base 108 therefore include a maximum displacement stop in the Z direction. As illustrated in the figures 14 And 15 The stop can take the form of an L-shaped leg 1504 of the base 108 (with a Z-shaped portion in a plane parallel to the XY plane), which cooperates with a receptacle 1406 of the support plate 202 that includes a portion in a plane parallel to the XY plane, thus providing a stop when the Z-displacement is too large. For example, the permissible Z-displacement is less than 1 mm.

[0104] The mounting of the support plate 202 onto the base 108 can be achieved by positioning the support plate 202 (or more generally, the entire moving assembly) above the base. The mounting holes 1502 on the base and the mounting holes 1402 must then be aligned in pairs to allow the insertion of the rod (for example, to insert a screw). This alignment can add a few seconds to the operator's time. To simplify the process, the measuring station 100 can include a guide between the moving and fixed assemblies. The guide can take the form of a guide rod 1408 extending in Z and suitable for cooperating with a guide hole 1506 of the base 108. The guide rod 1408 can be located close (at a distance D) to the attachment hole 1402 of the corresponding island 808 (for example less than 1 cm) so that the influence of manufacturing clearances is minimal.Similarly, the 1502 hole in the base 108 is close to the guide hole 1506 (the same distance D). The guide rod 1408 protrudes in Z relative to the level of the attachment hole 1402. In particular, even though the island 808 is configured to be fixed in XY movement to the main body 902, the elastic members 904 actually impart elasticity in XY; to counteract this undesirable movement that can disrupt the assembly, the guide rod 1408 is mounted on said island 808. The guide rod 1406 also allows the rotation of the island 808 to be blocked during screwing.

[0105] Conversely, the base 108 could have the guide rod and the island 808 the guide orifice.

[0106] An opening 1410 is provided near the island 808 to house the load cell, so that it is positioned between the measuring plate 106 and the base 108.

[0107] . THE figures 15 à 17 The figures illustrate the base 108 or certain components forming the base 108. In one embodiment, the base is a single piece (for example, made of metal to ensure sufficient rigidity). However, such a base is heavy and expensive. To overcome these difficulties, given the various functions of the base (structural support of the measuring station 100, aesthetic function, sealing function, function of joining the components, weighing function, etc.), the base 108 can be made up of several parts. In the embodiment illustrated in the figures, the base 108 comprises at least one frame 1508 and a stiffening plate 1602.

[0108] The stiffening plate 1602, which extends in an XY plane, is positioned between the frame 1508 (or within an open volume defined by the latter) and the support plate 202. The load cells rest directly on the stiffening plate 1602, which thus provides the necessary rigidity for accurate weight measurement, even on a soft (carpet, for example) or uneven (old parquet, for example) surface. The stiffening plate 1602 can be made of metal, for example, steel or aluminum. Aluminum has the advantage of being lightweight. As illustrated in the figure 16 The stiffening plate 1602 has ribs 1604 which, with the same amount of material, increase the plate's stiffness. The ribs 1604 are extensions of the plate along the Z direction. For example, the stiffening plate 1602 can be divided into at least two flat areas 1606, 1608 offset from each other along the Z direction and connected by the ribs 1604. The flat areas 1606, 1608 also define recesses for housing the components of the measuring station. For example, the winder 802 fits into the circular recess 1610 of the figure 16 The thickness of the 1602 stiffening plate (including the ribs) can be between 5mm and 15mm, for example 10mm. The material thickness can be between 0.5mm and 2mm, for example 1mm.

[0109] The geometry of the ribs, and therefore of the flat areas 1606 and 1608, depends on at least two factors: the mechanical stress factor and the space constraints. The ribs can be arranged in a grid pattern, maximizing the vertical (Z-shaped) sections that are resistant to bending, while leaving sufficient space in the Z-shape to accommodate the components (notably the winder 802).

[0110] The 1508 frame can be a single piece or made up of several parts. It serves an aesthetic function (as a housing that conceals the internal components of the measuring station 100) and can also serve to secure the parts together. The 1508 frame is, for example, made of plastic (a lightweight material). As illustrated in the figures 15 And 17The frame 1508 comprises a base 1510 (extending essentially in the XY plane) and a side wall 1702 (extending essentially in the Z direction from the edge of the frame 1508). The tab 1504 can extend from the frame 1508 (specifically the base 1510). The tab 1504 then passes through a corresponding hole 1614 in the stiffening plate 1602. The attachment holes 1502 can also be mounted on the frame 1508, for example, by being mounted on a spacer 1512 that extends in the Z direction from the base 1510. The spacer 1512 passes through a hole 1616 in the stiffening plate to contact the island 808 for assembly.

[0111] The elements 1514 of the frame 1508 are heat-welded studs (illustrated in the molten position). In practice, they take the form of a plastic rod that is inserted into a corresponding through hole 1612 in the stiffening plate 1602. An operator or a machine then melts the end of the rod, which expands and holds the stiffening plate 1602 and the frame 1508 together (soldering). Alternatively, screws can be used.

[0112] As seen in figure 2 The edge of the support plate 202 is recessed in X and Y relative to that of the base 108. Consequently, the interior of the support station 100 could be visible. To prevent this, the side wall 1702 may include a collar 1704 extending in a plane parallel to the XY plane from one end of the side wall 1702 towards the interior of the base 108. To help hold the stiffening plate 1602, the side wall 1702 may include a plurality of clips 1706 that clamp (by clipping) the stiffening plate 1602.

[0113] In one variant, the spacer 1512 is an independent part wedged between the frame 1508 (the bottom 1510 in particular) and the stiffening plate 1602. This allows the frame 1508 to be manufactured as a single piece by injection by allowing the movement of the injectors (otherwise the spacer blocks their passage).

[0114] Each 1514 pad is a thermal welding pad. It is a plastic piece that is melted so that it changes shape and locks the part inserted onto it.

[0115] The frame 1508 may include the chamfer 204 which facilitates the gripping of the measuring station 100. The chamfer 204 is present between the bottom 1510 and the side wall 1702 and allows the passage of fingers.

[0116] The electronic circuit of the load cells can be that described in applications PCT / FR2013 / 051754 or PCT / FR2021 / 050661.

[0117] As mentioned previously, the measuring station 100, and more specifically the base 102, may include a display 114 configured to show information to the user. The display 114 is attached to the support plate 202. The measuring plate 106 is positioned above the display 114. In an embodiment illustrated in figures 8 And9 The support plate 202 includes a housing 810 suitable for receiving the display 114. In order for the display 114 to be invisible when not powered and visible when powered, the measuring plate 106 is treated differently between an area with regard to the display 114 and the rest of the measuring plate 106.

[0118] In one embodiment, the sensors 104 include electrically conductive paths 602 (called "electrodes") on the base 102 (see in particular figures 6 et 7The electrodes 602 can take the form of a metallic deposit on an upper face 1104 of the measuring plate 106. The upper face 1104 of the measuring plate 106 is defined as the face that receives the user's feet (the visible face). To ensure the electrical connection with the PCB, the electrodes 602 pass through an edge of the measuring plate 106 and extend to a lower face 1204 of the measuring plate 106. The edge of the measuring plate 106 can have a rounded shape to ensure proper metallic deposition and electrical continuity. Furthermore, a rounded edge helps prevent injury when handling the measuring station 100. "Rounded" means an arc or similar shape. The rounded edge also simplifies the metallic deposition during manufacturing. French patent application FR2106653 describes these electrically conductive paths in detail.

[0119] The electrodes 602 are connected to the PCB via an electrical connector, which connects the electrically conductive path on the underside 1204 to the PCB mounted on the support plate 202. The switch 566 connects and disconnects the electrodes to various systems (ECG acquisition system, impedance measurement system, ESC system, etc.). In this way, each electrode can have several different functions depending on the switching position of the switch 566. The switch 566 may, for example, contain a plurality of switches controlled by the MCU.

[0120] The upper face 1104 of the base 102 comprises a left group LG of electrodes (intended to be in contact with the left foot) and a right group RG of electrodes intended to be in contact with the right foot. When the base 102 is positioned under normal operating conditions, the user places their feet on a left side of the scale and a right side of the scale (with their toes on the display side 114). figures 10 And 11 represent electrically conductive paths L1, L3, L5, L7, L9, L11, L13, L15, L17 which form the electrodes of the left group LG of electrodes and electrically conductive paths R2, R4, R6, R8, R10, R12, R14, R16, R18, which form the electrodes of the right group RG of electrodes.

[0121] The electrodes of the base 102 can take the form of bands parallel to each other along the X direction (along the width of the base 102).

[0122] In the illustrated architecture, the pairs of paths L1 and L3; L15 and L17; R2 and R4; R16 and R18 are not independent but are permanently electrically connected, so that the base 102 effectively comprises seven independent electrodes in the left group LG and seven independent electrodes in the right group RG. These permanent electrical connections can be made via the electrical paths on the measuring board 106 (for example, on the underside 1204, not shown) or via the PCB of the measuring station 100.

[0123] In one example, the electrically conductive paths of the upper face 1104 corresponding to the electrodes 1301-1312 have a dimension (on the upper face 1104) along the length Y of between 1.5cm and 2cm (for example 1.7cm); the spacing between two successive bands can be between 0.5cm and 1cm (for example 0.85cm); the electrodes can have a dimension along the width X greater than 10cm. In particular, each group LG, RG can include at least four independent electrodes in order to be able to perform an IPG in the foot (two electrodes connected to the alternating current source 560 and two electrodes connected to the voltmeter 562). In another embodiment, each LR, RG group may include at least two independent electrodes (to perform an ESC with anode / cathode and a high impedance electrode, or to perform a BIA or an IPG between the legs), or three independent electrodes.
